Web africa poor service no follow up on request

I have been trying to get my subscription canceled and cannot get hold of the relevant personal. On their wats app line which dey only use they just try and convince you to stay with them and don't help much . I eventually contacted the sales department which was their only contact and received a ref no for a cancelation request on the 7th November 2022 and I was told that I would receive a email shortly confirming the cancelation but still nothing ...I have tried to contact them regarding the above but still nothing. Their app has a cancelation request bit does nor work . Very dissatisfied.
